Different Welding Services Used Widely in Industrial Fabrication
Both industry and manufacturing serve as the society’s foundation. With such, we are able to have high quality living and holds promising future. However, the manufacturing as well as industrial sectors will not come in existence without structures, equipment as well as resources made by industrial fabrication and for that, industrial fabrication would not be available without welding.
Let us look on how welding plays an important role in industrial fabrication and the different kinds of welding services.
SMAW – this is also known as Shielded Metal Arc Welding or sometimes called as stick welding. Here, the stick is referring to the electrode coated in protectant flux. Electrode holder is holding the stick in place and then, an electric arc is achieved by using either alternating or direct current. In return, this is making the electrode melt slowly while also melting the metals that need to be joined.
At the same time, the flux coating is releasing a gas vapor along with the slag creates a shielded environment that serves as protection to weld the area from any sort of contamination.
GTAW – this is called as Gas Tungsten Arc Welding and as the name suggests, it uses tungsten electrode in producing the weld. If you’re going to compare SMAW welding, the electrode is not consumed in the welding process. Instead, the welded area is being protected from atmospheric contamination by inert gas which is typically Helium gas or Argon.
GMAW – referred as Gas Metal Arc Welding, it makes use of consumable wire electrode fed through welding gun. Inert shielding gas such as argon or mixture of carbon dioxide and argon is being sprayed to the welding puddle in order to protect it from contamination.
MIG welding becomes a typical welding method in different industrial setting because of its relative ease and versatility. On the other hand, it’s not ideal to be used for outdoor setting as well as other locations that have high air volatility.
FCAW – Flux Cored Arc Welding or FCAW has strong resemblance with MIG welding but, it features using special tubular wire that’s filled with flux. The flux might be sufficient on its own to protect the welding puddle from contamination or shielding gas may be used depending on the filter material and other circumstances.
SAW – the Submerged Arc Welding or SAW is using consumable electrode that is automatically fed. It is using characteristic blanket of granular fusible flux which consists of various compounds similar to lime, silica, calcium fluoride as well as manganese oxide. In order to protect the welding area, the combination is totally submerged.
